Okay yeah I could see that would be a pain in the ass.
I have purchased a couple of things from them and have been generally satisfied. I ordered something and was told "it will come in X weeks" and when I e-mailed them after putting my deposit down and waiting, somebody said "no we can't get that - want something else?" I was expecting a small discount on something else for the letdown and lack of notifying me that it won't be obtainable after waiting so long, but no such luck. Ah well.
